StegoVault: Hide Secret Files

Secure messaging and file protection, invisibly embedded inside an image.

StegoVault lets you send encrypted text, passwords, voice notes, and confidential files to someone you trust by hiding them inside an ordinary picture. The recipient opens the file in StegoVault, enters the shared secret key, and unlocks your message. Without the key, the hidden content remains completely unreadable.

HOW IT WORKS
Write your secret message, record a voice memo or attach any files, and choose a password. StegoVault encrypts everything and embeds it directly into the pixel data of a PNG carrier image using steganography. Share the resulting archive safely via email, WhatsApp, Telegram, Signal, or cloud storage. The recipient uses the same key to decrypt it.

MILITARY-GRADE SECURITY UNDER THE HOOD
• AES-256-CBC Encryption: Every payload is encrypted before a single bit is written into the image.
• PBKDF2 Key Derivation: Protects your passphrase with cryptographic salting and key stretching.
• Encrypt-then-MAC (HMAC-SHA256): Verifies data integrity before decryption. If the file is altered or the wrong key is entered, StegoVault immediately detects it and refuses to decrypt.

KEY FEATURES
• Hide text, passwords, and multiple file attachments (PDFs, documents, photos, etc.) inside a single PNG image
• Built-in Voice Recorder & Audio Player: Record and play back encrypted voice notes directly inside the app
• Smart Lossless Sharing (.zip): Automatically packages your stego-image so messenger apps never strip or compress your hidden pixel data
• Pick any photo from your camera or photo library as the carrier image
• Resizable workspace with an adjustable splitter between your text and attachments
• 100% Local & Offline: Everything is processed on your device — no accounts, no cloud servers, zero data collection

WHO IS IT FOR?
For anyone who wants to share or store sensitive information privately: passwords, recovery phrases, private voice memos, confidential documents, or personal messages meant for one recipient only.

Download StegoVault and keep your private information truly private.
